1、非谓语动词精讲精炼01核心考核要点解读近年来高考考查非谓语动词重点主要有不定式的完成式、被动式、进行式、否定结构及省略形式;不定式和分词作后置定语的区别;只能接动名词的动词和接动名词、不定式有区别的动词的用法;动名词的被动用法及分词作为定语、状语、宾补的用法。尤其是作状语的用法,在非谓语动词的考题中占的比例最大;其次是非谓语动词作补语和宾语的用法,也占一定的比例。不管怎么考,基本上离不开非谓语动词的基本用法,只是题干的设置注重了句子结构的复杂化和语境化。所以做非谓语动词题不仅要理清句子的结构,还要理解句子的意思。毋庸置疑,来年高考中,非谓语动词定是一个考查热点。 重要知识要点突破定义:在英语中

3、生Im glad to see you.当不定式逻辑上的主语是这个不定式所表示的动作的承受者时,不定式须用被动形式。如:He asked to be sent to work in Tibet.This book is said to have been translated into many languages.进行to be doing表示谓语的动作(情况)发生时,不定式表示的动作正在进行He pretended to be reading a book when I came in.完成to have doneto have been done先于谓语动作发生We seem to ha
4、ve met each other before.完成进行to have been doing先于谓语动作发生而又延续到谓语动作发生后He is said to have been studying abroad,but I dont know which country he is studying in.2.不定式的句法功能1)作主语:To finish the work in ten minutes is very hard.在十分钟内完成这项工作很难。动词不定式短语作主语时,常用it作形式主语,例如上面一句可用如下形式:It is very hard to finish the wor
5、k in ten minutes.2)作表语:Her job is to clean the hall.她的工作就是打扫大厅。3)作宾语:常与不定式作宾语连用的动词有:want, hope, wish, offer, fail, plan, learn, pretend, refuse, manage, help, agree, promise, prefer,afford,ask,decide,expect,intend,等。如果不定式(宾语)后面有宾语补足语,则用it作形式宾语,真正的宾语(不定式)后置,放在宾语补足语后面,如:Marx found it important to stud
6、y the situation in Russia.马克思认为研究俄国的形势很重要。动词不定式在介词but后面时,如果介词之前有行为动词do的各种形式,那么这些介词后的不定式不带to;否则就要带to。另外在cant choose but和cant help but等后面的不定式也省略to。如:I have no choice but to stay here.我别无选择只有待在这儿。动词不定式作动词tell,show,understand,explain,teach,learn,advise,discuss等词的宾语时,前面常带疑问词。即:疑问词(how,when,where,what,who
